different view for recursive & non-recursive clients

[Ladislav Vobr]

I have a situation, when I would like to have different answer for 
recursive and non-recursive clients, it basically simplify the user 
migration.

Is there anyway this could be achieved ? It would help me to show the 
how-to-migrate page to the end users (recursive clients), while keeping 
the real answer for the non-recursive clients (caching name servers).
